  • Publication number: 20250258044
    Abstract: A thermal sensor comprising: a supply voltage input configured to receive a supply voltage; a differential circuit, the differential circuit comprising a first element configured to provide a first sensing signal, and a first reference element configured to provide a first reference signal; and a controller configured to: obtain a measured supply voltage value, the measured supply voltage value corresponding to a measurement of the supply voltage received by the supply voltage input; obtain a differential measurement between the first sensing signal and the first reference signal; and determine a sensor output value based on the measured supply voltage value and the differential measurement. A method for operating a thermal sensor is also described.

  • Publication number: 20250208077
    Abstract: A thermal conductivity fluid sensor for detecting a first component of a mixture, the thermal conductivity fluid sensor comprising: a first heating element; and a controller, the controller configured to: control a temperature of the first heating element such that the temperature of the first heating element changes from a first temperature to a second temperature over a first transient time period; obtain a first reading indicative of a first thermal transport property of the mixture during the first transient time period; obtain a second reading indicative of second thermal transport property of the mixture when the first heating element is at the second temperature; and determine, based on the first reading and the second reading, a concentration of the first component of the mixture. A method for determining a concentration of a component of a mixture is also described.

  • Publication number: 20240133854
    Abstract: A fluid sensor for sensing a concentration or composition of a fluid, the sensor comprising a first temperature sensing element located on or within a first dielectric membrane and a second temperature sensing element located on or within a second dielectric membrane. An output circuit is configured to measure a differential signal between the first temperature sensing element and the second temperature sensing element. The fluid sensor comprises a first region configured to be exposed to the fluid, and a second region configured to be isolated from the fluid, where the first dielectric membrane is located in the first region, such that in use, the first dielectric membrane is exposed to the fluid, and wherein the second dielectric membrane is located in the second region such that in use, the second dielectric membrane is isolated from the fluid.

  • Patent number: 10928372
    Abstract: We disclose herein an electronic device comprising: a state machine for receiving an output signal from a sensor; a comparator operatively coupled with the state machine; and a first processor operatively coupled with the comparator. The state machine is configured to receive the output signal from the at least one sensor to obtain sensor measurement data and configured to pass the obtained sensor measurement data to the comparator. The comparator is configured to process the obtained sensor measurement data into first processed sensor data, and configured to compare the first processed sensor data with a first predetermined threshold limit. The comparator is configured to inform the first processor about the obtained sensor measurement data if the first processed sensor data exceed the first predetermined threshold limit.
